Strength Analysis of a Combined Large Barge for Building No.3 Bridge over Yangtze River in Nanjing

由四只甲板驳通过两道纵向联接杆系和四组横向联接杆系所组成的工程船 ,用于南京长江三桥主桥墩的定位和施工平台。本文在对船舶荷载工况详细分析的基础上 ,对该船结构件(船体、联结梁 )进行了强度分析 ,提出了合理的建议 ,以确保南京长江三桥塔基的施工精度及要求。

A large barge is combined with four deck barges by connecting them together with two longitudinal bar systems and four transverse bar systems and is specially used for building No.3 Bridge over the Yangtze River in Nanjing. In the paper, the strength of both the hulls of the barges and the bar s connecting them together is analyzed. And on this basis, some recommendations for ensuring the project's qu ality are proposed.
